Open the reportLowMissing InitializersClayStack · Quantstamp · 26 Sep 2022Fixed
`ClayManager` is missing a call to `__UUPSUpgradeable_init()` in the `initialize()` function. Though the function may be empty, it is important to call the initializer in case this changes in future version upgrades.
Open the reportLowMissing Input ValidationClayStack · Quantstamp · 26 Sep 2022Fixed
Some functions do not validate their inputs, which can result in unexpected behavior by the contracts. A non-exhaustive list includes: * `ClayManager.initialize()`: Validate that `_csToken` is a non-zero address. * `ClayManager._claim()`: Validate that `claimVault` is a non-zero address. * `ClayManager.earlyClaim()`: * Validate that order exists. * Validate that `claimVault` is a non-zero address. * Validate that the order cannot be claimed through ordinary means.

LowPrivileged Roles and OwnershipClayStack · Quantstamp · 26 Sep 2022Fixed
Certain contracts have state variables, e.g. `TIMELOCK_UPGRADES_ROLE`, which provide certain addresses with privileged roles. Such roles may pose a risk to end-users. The `ClayManager` contract contains the following privileged roles: * `onlyProxy` modifier-guarded functions * `initialize()` -- initialize the contract's variables post-deployment. * `upgradeTo()` -- upgrade the implementation of the proxy to a new contract. * `onlyRole(CS_SERVICE_ROLE)` modifier-guarded functions * `setBridgeFee()` -- set the fee to manually trigger the bridge by user in matic * `setBridgeRequirements()` -- set the days and amounts required for bridge transfers * `setMinClaimDays()` -- set the minimum number of days to claim tokens when netted locally * `pause()` -- pause the contract * `unpause()` -- unpause the contract * `onlyRole(TIMELOCK_UPGRADES_ROLE)` modifier-guarded functions * `setTreasury()` -- set the treasury wallet * `setClaimVault()` -- set the vault to which MATIC tokens will be sent * `upgradeTo()` -- upgrade the implementation of the proxy * `_authorizeUpgrade()` -- require a certain sender to be used (when upgrading the implementation) The `CsToken` contract contains the following privileged roles: * `onlyClayMain` modifier-guarded functions * `mint()` -- mints tokens to an address, increasing the total supply * `burn()` -- burn an amount of tokens from an address, reducing the total supply The `UserProxy` contract contains the following privileged roles: * `onlyProxy` modifier-guarded functions * `initialize()` -- initialize the contract's variables post-deployment. * `upgradeTo()` -- upgrade the implementation of the proxy to a new contract. * `onlyRole(TIMELOCK_ROLE)` modifier-guarded functions * `processInsurance()` -- process insurance towards ClayMatic donation and fees * `onlyRole(TIMELOCK_UPGRADES_ROLE)` modifier-guarded functions * `setClaimVault()` -- sets the vault to which matic tokens will be sent * `setTreasury()` -- set the treasury wallet * `upgradeTo()` -- upgrade the implementation of the proxy * `_authorizeUpgrade()` -- require a certain sender to be used (when upgrading the implementation) * `onlyRole(CS_SERVICE_ROLE)` modifier-guarded functions * `pause()` -- pause the contract * `unpause()` -- unpause the contract The `ClaimVault` contract contains the following privileged roles: * `claimFunds()` requires the sender to be `clayManager`.
Open the reportLowReliance on `fxRootTunnel` to Be Working as ExpectedClayStack · Quantstamp · 26 Sep 2022Fixed
The `ClayManager` contract is responsible for completing the process of a batch order that is specified by `batchID` in polygon, using `ClayManager._processMessageFromRoot()`. This function is designed and expected to be called only once. However, these functions have no protection against replay attacks. Though `_processMessageFromRoot()` prevents the same `_stateId` from being used twice, it does not prevent the same `_batchId` from being passed into `_registerClaimProceeded()`. `_registerClaimProceeded()` being executed more than once for a `_batchId` is an unexpected condition and could cause negative consequences to the platform.
Open the reportLowUnchecked Return ValueClayStack · Quantstamp · 26 Sep 2022Fixed
Most functions will return a `true` or `false` value upon success. It is important to ensure that every necessary function is checked. `UserProxy.deposit()` does not check the return value of its call to `clayMatic.deposit(amount)`.
Open the reportLowUnlocked PragmaClayStack · Quantstamp · 26 Sep 2022Fixed
Every Solidity file specifies in the header a version number of the format `pragma solidity (^)0.8.*`. The caret (`^`) before the version number implies an unlocked pragma, meaning that the compiler will use the specified version _and above_, hence the term "unlocked".
